         2 . The method according to  claim 1 , wherein the signal to the network management entity of the first mobile communication network is delivered from the management entity over at least one of: Service Capability Exposure Function, Network Exposure Function. 
     
     
         3 . The method according to  claim 1 , wherein data identifying at least one entity in a communication channel to reach the management entity by the terminal device is delivered to the terminal device. 
     
     
         4 . The method according to  claim 3 , wherein the data identifying the at least one entity in the communication channel comprises a definition for at least one of: an access point name of the management entity from the first mobile communication network, a data network name of the management entity from the first mobile communication network. 
     
     
         5 . The method according to  claim 3 , wherein the data identifying the at least one entity in the communication channel is delivered in one of: the signal to a network management entity of the first mobile communication network; a dedicated signal after the generation of the signal to the network management entity of the first mobile communication network. 
     
     
         6 . The method according to  claim 1 , wherein the data comprising at least part of a definition of a subscription corresponds to a digitally implemented embedded subscriber identity module. 
     
     
         7 . An apparatus for a network-controlled management of a subscription applied by a terminal device, the apparatus is configured to:
 generate a signal to a network management entity of a first mobile communication network serving the terminal device based on a subscription applied by the terminal device, the signal comprising data indicative to the network management entity to cause a generation of a network initiated attach request to the terminal device,   receive, upon a completion of an attachment to the first mobile communication network by the terminal device, a signal from the terminal device,   establish, in response to the receipt of the signal from the terminal device, a communication channel on a user plane with the terminal device,   transmit data to the terminal device, the data comprising at least part of a definition of a subscription requested to be applied by the terminal device in order to re-provisioning of the subscription applied by the terminal device to cause an attachment to a second mobile communication network.   
     
     
         8 . The apparatus according to  claim 7 , wherein the apparatus is configured to deliver the signal to the network management entity of the first mobile communication network over at least one of: Service Capability Exposure Function, Network Exposure Function. 
     
     
         9 . The apparatus according to  claim 7 , wherein the apparatus is configured to deliver data identifying at least one entity in a communication channel to reach the apparatus by the terminal device to the terminal device. 
     
     
         10 . The apparatus according to  claim 9 , wherein the data identifying the at least one entity in the communication channel comprises a definition for at least one of: an access point name of the management entity from the first mobile communication network, a data network name of the management entity from the first mobile communication network. 
     
     
         11 . The apparatus according to  claim 9 , wherein the apparatus is configured to deliver the data identifying the at least one entity in the communication channel in one of: the signal to a network management entity of the first mobile communication network; a dedicated signal after the generation of the signal to the network management entity of the first mobile communication network. 
     
     
         12 . The apparatus according to  claim 7 , wherein the data comprising at least part of a definition of a subscription corresponds to a digitally implemented embedded subscriber identity module. 
     
     
         13 . A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the program code instructions being configured, when the computer program product is executed on a computer, to cause the computer to at least;
 generate a signal to a network management entity of a first mobile communication network serving the terminal device based on a subscription applied by the terminal device, the signal comprising data indicative to the network management entity to cause a generation of a network initiated attach request to the terminal device,   receive, upon a completion of an attachment to the first mobile communication network by the terminal device, a signal from the terminal device,   establish, in response to the receipt of the signal from the terminal device, a communication channel on a user plane with the terminal device, transmit data to the terminal device, the data comprising at least part of a definition of a subscription requested to be applied by the terminal device in order to re-provisioning of the subscription applied by the terminal device to cause an attachment to a second mobile communication network.
